Instead of getting an answer on Saturday, Mr. David, a 6-foot-2, 280-pound former Navy varsity wrestler, found himself being beaten with a baton by a federal officer dressed in camouflage fatigues as another doused him with pepper spray, according to video of the encounter.
Mr. David was taken to a nearby hospital, where a specialist said his right hand was broken and would require surgery to install pins, screws and plates.
“I’m appalled and disappointed at the feds’ behavior — that whoever led them and trained them allowed them to become this way,” Mr. David said. “This is a failure of leadership more than it is a failure of their own individual behavior towards me.”
Luis Enrique Marquez, a self-described anti-fascist who has been a fixture at protests in Portland for years, said the purpose of the federal officers’ arrival had appeared to be to scare the protesters. But he said the officers had instead galvanized them by displaying the types of actions that have concerned protesters for years.
“With every act of violence they commit, our numbers seem to grow, people seem to get more angry,” Mr. Marquez said.
Demonstrators in Portland, including some who identify as antifa, the loose coalition of self-described anti-fascist activists, have had years of conflict with law enforcement. But after the killing of George Floyd in Minneapolis set off a nationwide movement for racial justice and police accountability, the protest in Portland drew thousands to the streets.
That created powerful scenes including images of protesters blanketing the Burnside Bridge, each lying face down on the pavement for eight minutes and 46 seconds in remembrance of Mr. Floyd.
